Title: Adjustable monolithic multi-wavelength laser arrays
Inventor: LI SAN-LIANG
IPC: H01S5/12
Filed: 1998-12-03
Granted: 2000-06-11
Abstract: An adjustable monolithic multi-wavelength laser diode array having formed on a substrate a plurality of diode lasers, each has an active section and two mirrors with similar multiple reflection peaks.  A phase control section can also be included in each laser for fine tuning of the laser wavelength.  Each laser in the laser array can emit light at the same wavelength or can be easily tuned to form an array with multiple wavelengths.  To serve as an application example of this invention, sampled grating DBR lasers are designed to form a laser array with adjustable multi-wavelength outputs.  By varying from laser to laser the sampling periods of the sampled gratings in each laser, a uniformly-spaced multi-wavelength laser array can be achieved with a simple tuning mechanism.  The lasers can also emit light at the same wavelength or be tuned to other wavelengths by tuning the sampled grating mirrors.  The technique for fabricating the laser array is similar to that for conventional DBR lasers and is already well established. The invented multi-wavelength laser arrays can find applications in WDM systems to offer the advantages of high performance, high reliability, compact size, and high speed.

Title: Prosthetic leg with extension auxiliary mechanism
Inventor: OKUDA MASAHIKO
IPC: A61F2/64
Filed: 1999-03-23
Granted: 2001-06-07
Abstract: There is provided a prosthetic leg with an extension auxiliary mechanism 1100 capable of generating an extension torque only when an angle of bending of the knee is small. A knee joint 80 of a thigh prosthesis 170 is of a multi-axis structure, and a front and a rear link 130, 150 together with an upper thigh member 110 and a lower thigh member 120 constitutes a constrained chain. An extension auxiliary mechanism 1100 having a compression spring is supported between the lower thigh member 120 and the rear link 150. An extension torque generated by the extension auxiliary mechanism 1100 is determined by a product of a force caused by biasing of the compression spring and a distance from a line of action of the force to the center of rotation of the rear link 150. Here, at a stage where the bending angle of the knee exceeds, for example, 15 degrees, an axis of the compression spring is brought generally into alignment with a connecting portion 1700 between the rear link 150 and the lower thigh member 120. By doing so, the distance related to the extension torque becomes approximately zero and the extension torque itself becomes approximately zero.

Title: Thin film transistors with organic-inorganic hybrid materials as semiconducting channels
Inventor: CHONDROUDIS KONSTANTINOS
IPC: H01L51/30
Filed: 2000-02-15
Granted: 2001-10-21
Abstract: An FET structure in accordance with the invention employs an organic-inorganic hybrid material as the semiconducting channel between source and drain electrodes of the device. The organic-inorganic material combines the advantages of an inorganic, crystalline solid with those of an organic material. The inorganic component forms an extended, inorganic one-, two-, or three-dimensional network to provide the high carrier mobilities characteristic of inorganic, crystalline solids. The organic component facilitates the self-assembly of these materials and enables the materials to be deposited by simple, low temperature processing conditions such as spin-coating, dip-coating, or thermal evaporation. The organic component is also used to tailor the electronic properties of the inorganic framework by defining the dimensionality of the inorganic component and the electronic coupling between inorganic units.
